Hadleigh Schwartz
I’m a PhD student in Computer Science at Columbia University, advised by Xia Zhou. I’m fortunate to also work with Dan Rubenstein and Changxi Zheng. My research develops media provenance and content authenticity technologies (i.e., tools to determine whether a piece of media is real or fake, how it was created, etc.). Right now, I’m particularly excited about audio, image, and video watermarking. I’m a recipient of a Columbia SEAS Presidential Distinguished Fellowship and an Amazon CAIT PhD Fellowship.
I recently interned at Cloudflare Research
working on media provenance. Previously, my research centered on optical sensing and communication, including an internship at NASA’s Jet Propulsion Laboratory
where I developed a hardware-in-the-loop simulator for vision-based spacecraft navigation systems.
I completed my B.A. and M.S. in Computer Science at the University of Chicago, advised by Heather Zheng at the SAND Lab.
